MIBD-176 - ``````jsx cs`````````### 1. Understanding the Problem**a. What is the problem?**I need to determine the distribution of different grades in a classroom. This includes calculating the number of students who received As, Bs, Cs, Ds, and Fs.**b. What is required?**I need to develop a system that organizes and analyzes the grades of students in a classroom.**c. What are the constraints?**1. **Uniformity of Grades**: Grades should be comparable across different subjects.2. **Consistency of Scale**: Grades should be calculated using a consistent grading scale.3. **Data Integrity**: Data must be accurate and secure.**d. What are the variables?**1. **Number of Individuals**: Number of students in the classroom.2. **Grading Scale**: The scale used to assign grades (e.g., A, B, C, D, F).3. **Overall Scores**: The overall scores of each student.4. **Grade Distribution**: Distribution of grades in the classroom.**e. What is the formula?****General Formula**:```Grade Distribution = Number of students receiving a given grade / Total number of students in the classroom```### 2. Analyzing and Developing Solutions**a. What is known?**1. **Number of individuals**: 30 students in the classroom.2. **Grading Scale**: A, B, C, D, F.3. **Overall Scores**: 4 As, 7 Bs, 8 Cs, 5 Ds, 6 Fs.**b. What is required?**To calculate the distribution of different grades in the classroom.**c. What are the constraints?**1. **Accurate Counting**: Each student's grade must be accurately recorded.2. **Security**: Data must be secure to prevent tampering.**d. Algorithm:**```1. Determine the number of students receiving each grade (As, Bs, Cs, Ds, Fs).2. Calculate the distribution of each grade using the general formula.3. Output the distribution of each grade.```**e. Procedure:**```1. Determine the number of students receiving each grade (As=4, Bs=7, Cs=8, Ds=5, Fs=6).2. Calculate the distribution of each grade: (a) Frequency multiplying each grade by 100 / total number of students. (b) Probability distribution using calculating probability of each grade in the classroom.3. Output the distribution of each grade.```**f. Solution:**```1. **Total number of students**: 30. for As: 4 students / 30 students = 13.3% for Bs: 7 students / 30 students = 23.3% for Cs: 8 students / 30 students = 26.7% for Ds: 5 students / 30 students = 16.7% for Fs: 6 students / 30 students = 20.0%2. **As**: 13.3% **Bs**: 23.3% **Cs**: 26.7% **Ds**: 16.7% **Fs**: 20.0%3. The distribution of grades in the classroom: As: 13.3% Bs: 23.3% Cs: 26.7% Ds: 16.7% Fs: 20.0%```**g. What is the solution?**The distribution of different grades in the classroom is:As: 13.3%Bs: 23.3%Cs: 26.7%Ds: 16.7%Fs: 20.0%
